Anthropogenic effects on soils in the eastern Tibetan Plateau revealed by geochemical elemental characteristics.

The Tibetan Plateau (TP) constitutes a fragile and sensitive ecological environment, which is vulnerable to global climate change and human activities. To investigate the anthropogenic effects on the TP's environmental system is valuable for guiding human responses and adaptations to future environmental changes. In this study, we detailedly analyzed the geochemical elements of four representative soil sections developed on loess from Ganzi, Jinchuan, Aba, and Chuanzhusi in the eastern TP.

Clinicopathologic features of gastric glomus tumor: A report of 15 cases and literature review.

Glomus tumor is a relatively uncommon soft tissue neoplasm predominantly occurring in upper extremity (fingers), less reported in stomach. This study aimed to discuss the clinicopathologic features of gastric glomus tumor (GGT) and then provide reference for clinical practice. A retrospective analysis of all cases pathologically diagnosed of GGT was performed, pathological findings were correlated with clinical information, immunohistochemical studies, next-generation sequencing, and patient follow-ups.

Comparisons of topsoil geochemical elements from Northwest China and eastern Tibetan Plateau identify the plateau interior as Tibetan dust source.

The high-altitude Tibetan Plateau (TP) is a potential substantial source of dust that could have major effects on the global dust cycle and lead to environmental change. Aeolian loess on the TP is a valuable archive for studying the history of dust activities. Identification of TP dust sources will deepen understanding of dust transport and atmospheric circulation patterns and their environmental impacts.

A wireless blood pressure monitoring system for personal health management.

In this paper, we developed a wireless blood pressure monitoring system which provides a useful tool for users to measure and manage their daily blood pressure values. This system includes an ARM-based blood pressure monitor with a ZigBee wireless transmission module and a PC-based management unit with graphic user interface and database. The wireless blood pressure monitor can measure the blood pressure and heart rate and then store and forward the measuring information to the management unit through the ZigBee wireless transmission.

[Detection of cell apoptosis in the pathological tissues of patients with SARS and its significance].

Objective: To explore the role and mechanism of apoptosis in severe acute respiratory syndrome (SARS).

Methods: Klenow-FragELTM DNA Fragmentation Detection Kit and immunohistochemical alkaline phosphatase detection reagent kit were used to detect cell apoptosis and expressions of CD68, CD20, CD4, CD8 and CD45RA in the pathological tissues of SARS patients.

Results: Apoptotic cells increased significantly in the spleen, lung and lymph nodes of SARS patients as compared with normal tissues.
